Natural sound from slender tower speakers

You can count on the Polk RTi A5 for clean, precise music and high-impact home theater. This slender tower speaker uses patented Polk technologies for true-to-life sound, and its curved edges and real wood veneer finish give it a handsome, refined look.

Additional high-end features

Two sets of gold-plated five-way binding posts let you biamp or biwire the RTi A5 for the best possible sound. An anti-diffraction grille helps it deliver a large, three-dimensional soundstage with pinpoint-accurate stereo imaging. Adjustable spikes provide stability on both carpeted and hardwood floors.

Priced each

Floor-standing speakers  still standing tall

Sure, floor-standing tower speakers buck the industry trend toward smaller, visually inconspicuous speakers, but they're hard to beat if great sound is your primary goal. Tower speakers produce powerful sound with excellent bass, making them a great choice for serious music lovers and for folks who want high-impact home theater.

Clear crisp sound

These Polk Rti A5 speakers are a tremendous bargain considering how good they sound. I bought a pair back in 2011 (cherry finish) and they still look and sound great.

In my living room, speaker placement was important. They sound best if the backs of the cabinets are between 9 and 10 inches from the wall. (Measured from the cabinet itself, not the guard.)

Overall, the sound is a little bright. I had to turn the bass control on my receiver up to the one o'clock position to make male vocalists sound right. These speakers are great for most music. But you'll want to add a subwoofer if you like to listen to very loud rock music or if you like rap. I'm now running them with a Polk PSW125 subwoofer and there is plenty of low bass with that combination, with the subwoofer's level control less than half of the way up.

The upside is that the sound is very precise and controlled. With a good recording, you'll hear every detail of the music.

The downside is that these speakers ruthlessly expose any flaws in the recording or in the rest of your audio equipment. I had to replace my ancient Sherwood stereo receiver because these speakers revealed the distortion in the receiver.

Oh, before you consider buying the larger Polk RTi speakers to get more bass, take a look at the size and weight of those monsters. The RTi A5 can be moved by one person, and so can the PSW125 subwoofer.

Pros:Sound and look great

Cons:Detailed sound reveals flaws in recordings and the rest of your equipment

I purchased these speakers to replace a pair of infinity primus p363's that I had moved to another room. What a mistake. I should have bought another pair of the infinitys. Theses speakers do not sound bad, they are just missing the detail and midrange that I was used to. It's funny, my wife didn't notice that I switched speakers, as she is clueless to what brands we have. She had asked me the other day why the stereo sounded different. They do, however, have decent highs, maybe a little on the bright side. I use them for both music and movies and would rate them as 3.5 out of 5 stars. There are certainly other options to choose from, especially at this price point.

Polk Rtia5

Written By David, Crystal Lake, Il. on Friday, September 19, 2014

These speakers are physically beautiful, in the cherrywood. Their sound is smooth and coherent. The only complaint I had was that I wanted them to sound way better than my old Polk Rti4 bookshelf speakers, and they only sound a little better(in the bass). But that says more about the quality of the Rti4's than it does about the Rtia5's. The main adjective for these speakers is: SMOOTH.

Really like them

Replaced a set of JBL Northridge tower speakers. Paired with: 12+ year old Onkyo home theatre receiver. Polk ATI3 as satellite speakers. JBL Northridge 80w sub. Very clear mids and highs. The JBL sub provides the deep base and these speakers provide a clear base that allows me to turn down my sub from the setting I had with the d JBL towers. Cabinets are very nice and compliment the cherry floors I have in my house. I would buy again.

Was expecting better.

Like the title, I was expecting more. A Polk loyalist I was somewhat disappoineted with the overall sound. These were to replace my Polk RM5000 system which consists of 2 front satelite speakers and a non-powered sub-woofer. This system is over 20 years old and is driven by the Denon AVR-X4000. The RTi A5s just didnt offer the sound I expected. Not any noticabel difference from the old system. They did not sound clear at all. Absolutely no punch unless you really turned up the volume. I did make numerous adjustmenst, but to no avail. My listening room is carpeted with some large couches so that may be part of it but my audio adjustments should have made some improvement. They did sound a bit better after about 40 days of break-in, but sent them back for a set of Klipsch speakers which sounded 100% better right out of the box. I will give that review later.

RTiA5 review

My system consists of a Denon X-4000 receiver, Polk RTiA5's up front, Polk RTiA1's for surrounds, Polk 660 pro sub & a def tech CS8040HD center (Polk CSiA4 was too big for tv stand cabinet). The A5's absolutely shine in multi channel use. I've tested with all kinds of movies on blue-ray, even movies on cable sound great. I was originally gonna get the A7's, but after some debating I got the A5's & I must say I'm glad I went with the A5's. They fill the living room (21X15) with plenty of sound & are actually sounding better after two weeks of break in. They do produce a fair amount of bass for their size, but in order to really reach down low, you'll need a sub, especially if you want that extra umph for movies.

On a side note... If your gonna spend the money on any of the RTiA line of speakers do yourself a favor & buy a good quality HT receiver. The A5's sound awesome powered by the Denon. I am now a believer, & will never buy a consumer level ($400-$500) receiver from here on out. Before my A5's arrived I hooked up my 15yr old Cerwin Vega LS-12's to the Denon & Wow! What a difference.

Anyway...yes the A5's are very nice speakers. They sound great & look great too. Def recommend them.

Polk Audio RTiA5 Speakers

just received one day ago. Have connected to a Yamaha RN-500 receiver (80 Watts/channel). Initial impression is very good. My biggest concern was if the combination setup (receiver/speaker selection) would produce enough bass for music (sans subwoofer). I am happy to report with the bass turned up on the receiver they satisfy in this regards. Great Sound and the appearance is also a plus.

Polk Audio RTi A5

These sound great! I am running a pair of them with a Denon AVRX-1000, and they are great!! I may want to push more power to them though with a better receiver. Their loud, and sound great with music, and movies.

Pros:Beautiful dark cherry color (the picture shows them in light cherry, but they are actually dark)

Review of Polk RTi A5

I believe my break in period is over. I purchased a pair of these fine speakers a few weeks back and am very pleased with their sound. The mid range is warm and detailed with nuances of sound coming from what seems to be distant back stage effects. An extremely clean top end in the upper register without it being overdone or sizzle. No boomy base .... nice and tight .... True sound and for and at their price point I could not be happier. As usual Crutchfield delivered on time as promised. I am definitely a Crutchfield satisfied customer. Now, my speaker system is complete with a full 7.1 system using front height speakers all Polk !!! The sound is amazing !!! Thanks Polk and Crutchfield !!!!

Pleasantly Suprised

I was apprehsive about buying the Polk Audio RTi A5 Floor standing speaker, after I set up my Stereo gear I was quite pleasantly surprised by how good the speakers sounded. The speaker's present a good stage presence, base is tight and I was pushing the speakers with a Yamaha RS700 @ 100 Watts per channel. I would say if someone wanted to push the speaker at 200 watts (The speaker's are rated at 250 watts) with a Yamaha RS700 to buy a power amp and hold your ears. I found the system and speakers to play at a range much louder than my ears could take.

Pros:Have great sound reproduction, easy to set up. I highly recommend this speaker.

polk RTi a5

Absolutely love these speakers, besides being gorgeous their sound is nothing short of beautiful. They are so good looking that I actually rearranged my furniture to showcase, they outclass my other furniture!

Great Speakers!

Fantastic sound. I wanted bass, and I got bass. Almost no need for a sub-woofer. The Crutchfield tech rep who assisted me in selecting speakers to match my components and listening needs was right on the money. If you want well priced, high end speakers, these are the ones. High tones are very well reproduced in addition to the lows. No matter what type of music you listen to, or movies you watch, I do not think you will be disappointed with the RT1 A5's. A great match to the Sony STR-DN1030,...the RTi A5's reproduce its sounds extremely well.

Nice Speakers!

I was concerned about the quality when I ordered, as you cannot truely get a feel for that from the picture, but once they were out of the box I was very impressed with the quality of the RTI A5. I really like these speakers for listening to music and they do an excellent job as my front pair in a 7- speaker setup in a 14x20 room.

Good sound beautiful cabinet

Very good sound quality for the price, I am more impressed with the looks of the cabinet, they look more likes piece of high quality furniture than a speaker. I am still leaning the range of these speakers think they do well with the mid tones and are a little weak at highs but still worth the price. The shipping company that crutchfield uses was terriable it took them almost 2 weeks to get them to me. I called customer service and they told me they had to be shipped by carrier other than ups because of size. The grilles are the cheapest part of a other wise terrific speaker

Pros:Great looking cherry wood good sounding and a very good value got a free sub woofer

Under Rated

Written By Charles, Tinley Park, IL on Wednesday, January 11, 2012

This is a great product, I was disappointed to see so few reviews during my research. I originally had the tsi series in mind. If your like me and spend hours researching your purchase, enough to know more than the so called "experts" at some audio vendors, this is your sign. When it comes down to it, these speakers are simply amazing. A step up from the Tsi series they look beautiful, constructed well and look great with any furniture (made the girl friend happy). The A5 series is worth the extra money for higher quality and better highs, bigger volume cabinets which give them incredible bass. These shake the apartment enough to annoy the neighbors, let alone adding a sub too! My setup though is packed into a small 760sq ft apt, overkill but I went for the possibility for upgrades.

Pair these with the Csi A6 Center and movies come alive.

I have Rti4's in the rear, planned to move these to my 7.1 setup eventually with the Rti A9s in the front.

Powered by the Denon 2312 these far surpassed my expectations as an entry level home audio enthusiast.

Amazing

I was planning on buying the speakers that ran a little less, but decided on these. Kind of concerned since there are few reviews for them, hoping I wouldn't regret not getting the A7 speakers. These are wonderful! We have a smaller house, powering them with a Denon 1912. I could't be more pleased with them. Polk has always made great speakers and these should last us a very long time. Huge improvement over our XBR5's speakers. We hear details we never heard before in movies. A winner all the way!

Polk RTi Series Speakers

I was impressed with the speakers overall. Excellent craftsmanship. However, one of the side supports came without thread for the carpet spike. Polk has to improve their QA department. I called Polk directly and they said that they would mail me a replacement. The speakers have an overall excellent sound quality, nice and crisp, and I found no need for a sub-woofer, as so many people say that you need one, because they are bass-reflex. The sound quality does improve as the speakers break-in.

2nd WOW

These speakers really beat my expectations! I have just these and a psw125 sub (for now) coming from a onkyo TSX607 and the sound is great! The finish on the RTi A5 is second to none. I just watched Hurt Locker and Saving Private Ryan and could not believe my ears. The gun battles were so realistic. You will not be disappointed if you get these.

Product Research

Driver Technology

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to
determine what combination of speaker materials create the least amount of
resonance. Eliminating resonance in speakers results in a wide, smooth response
and low distortion.

Polymer Composite Woofers:
The speaker features two 6.5" polymer
composite woofers. Two 6.5" woofers have the surface area of a single large
woofer with the low mass and acceleration of small woofers, resulting in
tighter, more accurate bass response. Each woofer uses a butyl rubber surround.

Silk/Polymer Tweeter: The speaker has a single 1" silk/polymer dome tweeter that provides clear, detailed
highs. The tweeter features mylar bypass capacitors in the crossovers to extend
high frequency response and improve detail and transparency. The also tweeter
features low viscosity ferro-fluid cooling with a heat
sink on the Neodymium magnet for superior heat dissipation, power handling and
reliability.

Magnetically
Shielded:The
speakers are magnetically shielded, allowing you to place them near your
television without distorting the picture.

Enclosure Design

Damped Asymmetric Hex Laminate (DAHLI) Cabinet Design:
All-MDF construction with massive
asymmetric cabinet bracing ensures a resonance-free enclosure for accurate
sound. The asymmetric design is made from a 6-layer laminate
with 5 viscous layers to create the optimal
shear damping (OSD) system. The elegant styling aside, curved cabinets
not only result in a stronger, more rigid and
acoustically inert enclosure, but the curved walls also produce less
audible coloration from panel resonances.

Power Port Venting System:The
speaker has a rear-firing Power Port venting system built into its back plate
for precise deep bass response. This venting system allows air velocity
to slow gradually, vastly reducing air turbulence, and delivering greater bass
efficiency than conventional ports.

Acoustic Resonance Control (ARC): Internal cabinet resonance can impart a "thick" character to voices.
Polk's patented Acoustic Resonance Control port system overcomes this problem.
In addition to the Power Port venting system, each speaker has a front-firing
port that is tuned to suppress the internal cabinet resonance, resulting in
smooth, natural midrange reproduction.

Connections

Dual 5-Way Binding
Posts: The
speaker has two sets of gold-plated 5-way binding posts connected by gold-plated
jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the
speakers.

Mounting Options

Adjustable Leveling Spike Feet: The adjustable leveling spike feet
that can be screwed onto the bottom of the speaker's attached base provide
stability on any type of flooring. The spike feet adds approximately 0.875" to the speaker's overall height
when screwed all the way in.

Specifications & Dimensions

Width: The
main body of the speaker is 8.375" wide but the
speakers attached feet extend beyond each side of the speaker, giving the
speaker and overall width of 10.5625".
